Protein And Its Importance In The Human Body

Protein is an essential macronutrient and so it automatically becomes an important part of a healthy, balanced diet. When a nutrient falls in the category of macronutrients it simply means that our body needs the same in a larger quantity as compared to other essential nutrients. It is a known fact that a person’s overall weight comprises of 15% protein. So maintaining the same becomes an obligation in order to stay healthy and fit. Protein is an important component that aids in metabolism, provides energy as well as works towards building and repairing organs, bones and muscles. It is required to make hormones and enzymes. It also works towards strengthening the immune system. The chemical composition of protein includes amino acids also termed as the building blocks of proteins. It consists of carbon, hydrogen, oxygen, nitrogen and sulfur.

Best Sources of Protein

Protein intake is essential for our body to remain healthy and strong. Various options are available to include protein in one’s diet. However, it is necessary to go for healthy protein-options than those that may adversely affect the body when consumed in large amounts. Protein found in processed food, dairy products and meat with high-fat content is best when avoided. Let us take a look at some of the healthy sources of protein:

  • Fish like tuna, salmon
  • Legumes like beans, lentils, peas
  • Nuts like pecans, peanuts, cashews, walnuts, etc
  • Eggs from organic poultry.
  • Organic meat
  • Whole grains
  • Organic dairy
  • Low-fat dairy including yogurt, milk, cheese, etc

Interestingly one may argue that protein supplements are sufficient to suffice one’s protein-needs in the diet. However, though they do supply protein to the body it should never be considered as the sole source of protein and should be taken, in moderation, alongside other healthy protein options.

How Much Protein Can Be Consumed Per Day?

Too much of anything can do us more harm than good. The same is the case with protein intake. What one needs to bear in mind while consuming protein is that when taken in moderation it will surely work towards building and repairing the body. Factors that need to be taken into consideration for the same are gender, age and health primarily followed by other factors. The general allowance of protein intake for a person, per day, is 0.8 grams of protein per kilogram of a normal, healthy person’s weight which sums up to about 45-55 gms per day. A slight increase is permissible. Athletes and those resorting to working out using heavyweights are allowed up to 3.5 grams of protein per kilogram of body weight, depending on the level of their daily activity. The ketogenic diet as well as plant-based diets that seems to have gripped the society in recent times can have high-protein content in them and over the long run may have adverse effects on one’s health. What one must remember is that a diet that is high in protein is directly proportional to the intake of calories, exceeding which can lead to several risk factors which if left neglected can have dire effects on one’s health. So before one resorts to a diet high in protein it is best advised to consult a doctor or nutritionist who will be able to guide the person as to how much of what should be consumed so as to reduce the risks associated with an excess of protein in one’s diet.

The irony with a high-protein diet is that even when one feels less thirsty one ends up getting dehydrated. This is because the body gets rid of excess nitrogen in the body with water and other fluids and is more harmful in the case of an active individual.

  • Bad Breath

Restricting carbohydrate intake associated with a high-protein diet can lead to an unpleasant fruity order coming from the mouth and is often related to the body going into ketosis.

  • Kidney Damage

Those with underlying kidney problems may find a high-protein diet doing them more harm than good. This is because a weak kidney has to put more effort to get rid of the excess nitrogen and unwanted byproducts of a protein diet.

  • Cancer Risk

Protein diet that promotes the excessive intake of red and processed meat may cause colorectal, prostate and breast cancer and other health issues and this could be because of the existence of certain carcinogenic compounds found in red meat.

  • Loss of Calcium

Increased intake of protein can sometimes lead to a loss of calcium in the body and this may lead to health conditions like osteoporosis.

Be it proteins, carbohydrates or fats, everything should be consumed in adequately required quantities only. Along with a healthy food intake one must also inculcate the habit of routine exercising in one’s daily activities. And lastly, as a general rule of thumb, before resorting to any diet-plan one must not forget to consult a dietician or nutritionist to ensure the said diet-plan is suitable for them.
